PATENT OFFICE DISINTEGRATING MACHINE Application July 31, 1931. SerialNo. 554,221

1 Claim.

This invention relates to disintegrating machines, and has for an objectto provide a machine having improved means for disintegrating material,such for instance as cheese, although it is to be understood that theinvention is not limited to any particular material upon which it istooperate.

A further object of the invention is to provide a disintegratingmachine, having a rotating disintegrating disc of improved type.

A further object of the invention is to provide a disintegrating machinehaving improved means for feeding the material into contact with thedisintegrating disc.

The invention therefore comprises a disc having disintegrating talonsoutstanding therefrom, with communicating passages through the disc, acurved chute contiguous to the disc, having a partition therein, with afeeding device slotted to accommodate the partition to feed material tothe disc, a driving means for rotating the disc, and a receptacle forreceiving the disintegrated material from the disc.

The invention is directed to other objects, and possesses other featuresof novelty and advantage, some of which, together with the foregoing,will be hereinafter more fully set forth.

In the drawings:

Figure 1 is a view of the device partly in side elevation and partly insection,

Figure 2 is a view of the machine in top plan,

Figure 3 is a plan view of the preferred form of disintegrating disc,

Figure 4 is a plan view of a modified type of disintegrating disc, and

Figure 5 is a sectional view taken on lines 55 of Figures 3 and 4.

Like characters of reference indicate corresponding parts throughout theseveral views.

The improved disintegrating machine, which forms the subject matter ofthis application, comprises a base 10, upon which is erected a housing11. The housing 11 is preferably open at one end to receive slidablyinserted therein a container 12.

Mounted upon the housing 11 is a prime mover 13, having a pinion 14intergeared with a spur gear 15, carried upon the shaft 16 which extendsinto the passage 17. The passage 17 communicates with the interior ofthe housing 11 over the receptacle 12, and designed to dischargematerial thereinto.

Mounted upon the shaft 16, is a disintegrating disc 18 or 18'. extendingfrom the face opposite the gear 15 a plurality of talons 19. In the typeshown at Figure 3, the talons 19 are arranged spirally about the centeropening 20 which receives a fastening member, as the screw 21 to securethe disc to the shaft 16. Each of the talons 19 is arranged at one sideof a perforation 22, such perforations These disintegrating discs havebeing tapered from the working face of the disc to the back, asindicated more particularly in the enlarged detail sectional View,shown, at Figure 5. Merely as lending to the understanding of theconstruction without attempting to claim method of manufacture, it maybe pointed out that these talons are raised by an implement which isdriven into the face of the disc, forming the groove 23, and after thetalon is so raised, the perforations 22 are drilled contiguous thereto.

The disc 18 or 18' rotates in an opening formed in the side of thepassage 1'7, and communicating with this opening, is a feed chute 24,curved both transversely and longitudinally, both curvaturescorresponding to the arcuature of the discs. Within this chute, apartition 25 is erected. A feed follower 26 is fulcrumed at 2'7 andprovided with a handle 28, and necessarily with a slot to accommodatethe partition 25. Y

In operation, the machine will be driven to rotate the discs in thedirection indicated by the arrows at Figures 3 and 4 so that each of theperforations 22 isimmediately followed by one of the talons. Thematerial to be disintegrated is placed in the feed chute with thefollower raised to permit such insertion. The follower is then moveddownwardly upon the contained material 'by pressure exerted upon thehandle 28, and this pressure communicated to the follower will force thematerial against the rotatingdisc. The partition 25 is an importantfeature as it tends to prevent the contained material from rotating inconsonance with the rotation of the disc and holds it so that thepassing talons will each move therefrom its bit, such bit being forcedthrough the perforations 22 into the passage 17, falling therefrom bygravity to the receptacle 12.

The particular types of discs shown are, as noted in the objects ofinvention, especially designed for the disintegrating or grating ofcheese, but there are a great number of other commodities which will bedisintegrated by the use of this machine as efiiciently as cheese.

The disintegrating machine, herein illustrated, may be modified invarious ways without departing from the invention herein set forth andhereinafter claimed.

The invention is hereby claimed as follows:

A disintegrating machine comprising a rotating disc, a plurality oftalons outstanding from one face of the disc arranged in a voluteseries, each of said talons having a curved engaging face and beingimmediately preceded in the order of rotation by a perforation tapereddivergingly entirely through said disc, said perforation being precededby a groove tapered throughout its length with the wider endcommunicating with'the perforation.
